I'm so happy that Acid is back. I invested a lot of time and money in it, only to have Sony drop it, and it to become unusable. I used to use it as a ReWire slave to Cubase- the workflow was amazing and Acid made drum loops super easy. However, it currently does not funciton as a ReWire slave, as it used to. Honestly, ReWire in Acid is not very useful unless it can be used as a slave. Is there any plan to add this functionality? It really is awful to have one feature prevent me from using Acid again; I was looking forward to revisiting some old sessions. Also, the manual (still) clearly states that Acid can be used as a slave, while the forums indicate otherwise.
